' UNITED STATES PATENT EEcEQ EBENEZ ER BLAOKMAN, OF BROOKLYN, NEW YORK.

LAMP.

SPECIFICATION forming part of Letters Patent No. 2 68, 856, dated December 12, 1882.

Application filed June 22, 1882. (No model.)

T 0 all whom it may concern:

Be it known that I, EBENEZER. BLAcKMAN, of Brooklyn, in the countyof Kings and State of New York, have invented a certain new and useful Improvement in Lamps, of which the following is a specification.

An important object of my improvement is to provide for the use in a lamp of a round wick-burner with a translucent shade-holder and a shade supported on the latter.

My improvement consists in the combina tion, with a round wick-burner, of a translucent shade-holder fitted thereto and having an indentation above the tip-of the wick-tube, a button or spreader supported by the burner andextending some distance above the indentation of the shade-holder, a tube extending above the wick-tube and perforated below said button or spreader, the said holder, object.

My improvement also consists in the combination, in a lamp-burner, of a round wick-tube having longitudinal slotsin its exterior, a plate or plates fitted to the exterior of the said wicktube, provided with teeth which pass through and a shade supported on whereby I attain the desired the slots in the wick-tube, so as to engage with the wick, and having an external screw-thread and an internally-screw-threaded ring, which engages with the said plate or plates, and may be turned to elevate or depress the same, and thereby ring will also serve as an air-distributer and as a gallery for supporting the shade-holder aforesaid.

The improvement also consists in the combinatiomin a round wick-burner, of a deflector and a tube extending above the wick-tube of the lam p-burner to the deflector and perforated below the deflector.

The improvement also consists in the combination, in a round wick-burner, of a deflector, button, or cap above the wick-tube, and a tube arranged within the wick-tube and extending to the deflector, button, or cap, and perforated between the tip of the wick-tube and the deflector, button, or cap.

The accompanying drawings are made approximately on a scale of nine inches to the foot.

Figure 1 is a central-vertical section of a raise or lower wick. Preferab'lythislamp embodying my improvement, and Fig. 2

is an inverted plan of the burner of said lamp.

Similar letters of reference designate corresponding parts in both figures.

A designates the oil-reservoir of the lamp.

It may be of any suitable form, and the oil employed may be kerosene or any other suitable oil.

B designates the wick-tube of the burner. It is of round or annular form, and is mounted on a base-piece, O, which comprises an. externally-screw-threaded boss, whereby the burner may be secured in the collar a of the reservoir A. This wick tube has at opposite points openings or ducts I), leading from its exterior to its interior. Preferably this wick-tube will be supplied with a wick which is of annular form at the tip and has two lower port-ions oc- -copying positions on opposite sides of the wicktube between the openings or ducts b. Two flat wicks of a size adapting them to fill the wick-tube at the tip may, ployed. The inner wall of the wick-tube has fitted to the lower end a perforateddiaphragm, 0, through which airfrom the reservoir may gain access to it. Air may enter the reservoir through anysuitable opening-as, forinstanc-e,

a filling-mouth, d, the cover 6 thereof beingperforated or being removed or loosened when the air is desired to enter the reservoir.

1) designates two plates adapted to fit snugly against the'exterior wall of the wick-tube B, and provided with teeth], which pass through slots g,extending lengthwise of the exterior however, be em-' wall of the wick-tube, so as to engage with the wick. These plates are externally screwthreaded. it

E designates an internally-screw-threaded ring, which engages with the screw-threads of the said plates and rests upon supports F. These supportsF consist of arc-shaped pieces having their ends bent downward and secured by solder or otherwise to the exterior wall of the wick-tube B. Their ends serve as guides for the plates D. By turning the ring E in one direction the plates D will be raised, and by turning it in the other direction the plates will be lowered. This ring is made to constitute or form part of a perforated draft- -plate or air-distributer, E,

for supporting the devices whereby the requiand a gallery, E Y

the tip of the wick-tube B of the burner.

Above this indentation there is an upwardlyflaring flange, 70, which is surmounted by a rim, j. On the exterior of the tubular base portion h of the shade-holder are inclined lugs a, with which engage claws 0, extending from the gallery E By inserting the tubular base portion of the shade-holder on the gallery and turning it around the said lugs may be made to engage with the claws.

The shade G will preferably be made ot'opal glass and of conical or conoidal form, converging upwardly toward the upper end. The

lower end of the shade fits within the rimjof the shade-holder. It may be supported by its lower edge resting on theflange k of the shadeholder; or it may be supported by means of a shoulder, l. with which it is provided, resting on the rim j of the shade-holder. The shadeholder and shade are designed to fit so snugly together as to preclude the passage of air between them. The relation between the height of the opening in the upper end of the shade I and the diameter of such opening must be such as to insure the necessary draft of air to be induced to the burner. The shade-holder and shade represented in the drawings filed herewith are of suitable proportionsfor the burner shown, but will have to be varied to suit burners of different sizes.

J designates a button or spreader supported on a rod, m, arranged within the wick-tube. It'is secured to the rod by being simply slipped upon the end of the rod. Its upper portion is elevated considerably above the indentationt' of the shade-holder.

PreferablyI arrange within the wick-tube B a tube, I, extending upward from about the top of the ducts b. This serves to direct air entering the duct b and through diaphragm a up to the outer portion of the button or spreader. The air passing up the interiorofthe wick-tube, reaching the spreader, is deflected outward, and the air passing upthe tubular base portion h of the shade-holder is deflected inward above the tip of the wick-tube. As the button or spreader is higher than the indentation, the flame will thus. be caused to spread outward. Theindentation and spreader being practicallyequidistant from all parts of the wick-tube, a beautiful bright flame is produced, unequal heating of the shade-holder and shade is lessened, and the tendency of breaking them is very materially reduced. The shade-holder and shade may be readily removed to facilitate their cleaning or the cleaning of the burner.

Preferably thetube I is extended upward to the under side of the deflector J, 'and is perforated above the tip of the wick-tube. Air passing upward is distributed through the perforations of the tube I, and stimulates combustion throughout the flame. In this way a very white and luminous flame is produced. Thisimprovement maybeusedinbnrners for stoves as well as burners for lamps. When the tube I is extended above the wicktube, and perforated, thedeflector J, or a button or cap of suitable construction, may be supported upon the top of the said tube I. The rod m may then be dispensed with.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a round Wick-burner, of a translucent shade-holder fitted thereto, and having an indentation above the tip ofthe wick-tube, a button or spreader supported by the burner and extending some distance above the indentation of the shade'holdcaa tube extending above the wick-tube and perforated below the button or spreader, and a shade supported on the said holder, substantially as and for the purpose specified.

2. The combination, in a lamp-burner, of a round wick-tube havinglon-gitudinalslotsinits exterior, a plate or plates fitted to the exterior of the said wick tube, provided with teeth which pass through the slots in the wick-tube, so as to engage with the wick, and having an external screw-th read and an internally-screwthreaded ring, which engages with the said plate or plates and may be turned to elevate or depress the same, and thereby raise or lower the wick, substantially as specified.

3. The combination, in a lamp-burner, of a round wick-tube having longitudinal slots in its exterior, a plate or plates fitted to the exterior of the said wick-tube, provided with teeth, which pass through the slots in the wicktube, so as to engage with the wick, and havin g an external screw-thread and an internallyscrew-threaded ring engaging with the screwthread of the plate orplates, and forming part of or constituting an air -distributer and gallery for support for a draft-inducing device, substantially as specified.

4. The combination, in a round wick-burner, of a deflector and a tube extending above the wick-tube of the lamp-burner to the deflector and perforated below the deflector, substantially as specified.

5. The combination,in a round wick-burner,

of a deflector, button, or cap above the wick-.

tube, and a tube arranged within the wicktube and extending to the deflector, button,or cap, and perforated between the tip of the wick-tube and the deflector, button, or cap, substantially as specified.
